Step-by-step explanation:
Tn = a + (n - 1) d
Where
Tn is the nth term of the sequence
a is the first term of the sequence
n is the number/term of the sequence to be solved
d is the common difference
Answer:
45 horseshoe crabs and 45 sea stars
Step-by-step explanation:
The aquarium initially contained x crabs and x sea stars.
"After 15 horseshoe crabs and 27 sea stars are removed the ratio of horseshoe crabs to sea stars is 5:3"
(x-15):(x-27) = 5:3
(x-15)/(x-27) = 5/3
3(x-15) = 5(x-27)
3x-45 = 5x-135
90 = 2x
x = 45
Answers:
10. b. 
9. b. 
8. a. 
7. a. 
Step-by-step explanations:
10. Both segments are considered congruent, so turn both expressions into an equation:
Plug this back into the equation to get on both sides.
9. All edges in a square obtain congruent right angles and edges, so set 
equivalent to the given expression:
8. Both angles are considered supplementary, so turn both expressions into an equation and set it to one hundred eighty degrees:
7. In this rectangle, segment <em>EO</em><em> </em>is a segment bisectour, making these angles <em>Complementary</em><em> </em><em>Angles</em><em>.</em><em> </em>Therefore, set an equation up to find its complement:
I am joyous to assist you at any time.
If you observe the two given equations, the left hand side of both equation is the same and is equal to y.
Since the left hand side of two equations is the same, we can conclude that the right hand side of two equations must also be the same.
So, setting them right hand sides of both equations equal to each other and solving for x, we can find the solution to the simultaneous equations.
Therefore, the correct answer is option B
